What Are Aluminum Bronze Flanges?
Aluminum Bronze Flanges are pipe-connecting metal elements that consist of a copper-based alloy that may include slight amounts of other elements such as iron and nickel in order to increase the strength and corrosion resistance. This is an alloy, that is resistant to seawater, chemicals, oxidation, wear, and corrosion in the atmosphere; hence, it suits very harsh industrial conditions. In high pressure and high temperature pipe joints, aluminum bronze flanges are used to offer strong, leak-free, and durable pipe joints. These flanges are commonly applied in marine applications, offshore platforms, chemical plants, power generation stations, shipbuilding, aviation, oil and gas and heavy industrial piping networks where long life and high power serviceability is of critical importance due to their high mechanical qualities, fatigue resistance, low oxidation rate and good weldability.
